FIGURES
1 Axes notation for sandwich cores
2 Sketch showing shear specimens attached to loading plates
and plane of action of applied loads
3 Compression test apparatus showing an adjustable
supporting base and slotted round bars in position on
the specimen ends. Deformations are being measured
with Marten's mirror compressometers
4 Test apparatus for tension flatwise test of core
material for sandwich-type constructions showing
specimens and fitting for applying load

7 Possible modes of failure of sandwich composite under
edgewise loads: General buckling, shear crimping,
dimpling of facings, and wrinkling of facings either
away from or into the core
